Question

The acid-catalyzed aqueous hydrolysis of ethyl acetate is a classical textbook example of a "Pseudo-First Order" chemical reaction. Which defining structural condition is primarily responsible for rendering this bimolecular process kinetically first-order?

Prashant Kotian · Accepted Answer

Correct answer: C. Although two separate molecular species (ester and water) must successfully collide in the Rate Determining Step (Molecularity = 2), the massive overwhelming excess of water ensures its concentration barely shifts. Thus, it effectively merges with the specific rate constant, rendering the apparent order precisely 1.
